FMRI Research on Reading Processes

Doctoral student S. C. (Hans) Huang is conducting a thread of research employing brain imaging (fMRI - functional Magnetic Resonance Imaging) to identify similarities and differences in the human processing of alphabetic words, logograms (e.g., Mandarin characters), and HCI icons.

CI-TEAM Implementation: Educating a Competitive, Cyberinfrastructure Savvy Engineering and Construction Workforce

This is NSF-funded work Dr. Bias is carrying out with PI William O'Brien, Associate Professor in Civil Engineering. The goal of this project is to research and design advanced cyberinfrastructure - particularly in information integration and sensor networks - to support the civil infrastructure such as roads, bridges, and buildings.

Studying Design Intent for Software Evolution and Maintenance

Another NSF-funded thread that Dr. Bias is working on, this time with PI Dewayne Perry, Professor in Electrical and Computer Engineering. Our goal with this work is a better understanding of the documentation needs of maintenance designers for software systems and the construction of a model of how those maintenance designers interact with documented knowledge about legacy designs.

Usability support of Vignette

Dr. Bias and his students have been providing ongoing usability engineering support, including mostly remote usability testing from the Information eXperience Lab, of Vignette's (now Open Text's) emerging next generation of web content management software applications.

Fitts' Law Project

Perhaps the most well-known law in the field of human-computer interaction, Fitts' Law specifies the function for the time it takes to acquire a target (say, click on an icon) based on the size of the target and its distance from the current location of the cursor. With Doug Gillan, Chairman of the Psychology Department of North Carolina State University, Dr. Bias is conducting a series of studies to quantify the role of cost of an error, within Fitts' Law.

LIFEisGame: Learning of facial emotions using serious games

LIFEisGame project intends to design an interactive game employing real time facial synthesis and automatic expression analysis techniques to teach children with ASD (Autism Spectrum Disorders) to recognize emotions embedded in human facial expressions. Dr. Yan Zhang is working on examining how autistic children interact with the game and how to design better information architecture for the game. This project is funded by the UT Austin-Portugal International Collaboratory Grant for Emerging Technologies and is a collaboration with Dr. Jake Aggarwal from the ECE Department at UT Austin and Dr. Veronica Orvalho from the Computer Science Department at the University of Porto, Portugal.

Past IADU Research Projects

  • Dr. Bias recently capped his research on Microsoft's ClearType with an article in JASIST:

    Bias, R. G., Larson, K., Huang, S. C., Aumer-Ryan, P., & Montesclaros, C. (2010). An exploratory study of visual and psychological correlates of preference on onscreen subpixel-rendered text. Journal of the American Society of Information Studies and Technology, 61:4, 745-757.

  • In 2010 Dr. Bias and two master's students carried out a series of usability studies (including field testing, pluralistic usability walkthrough, and a survey) to assist the Texas State Library and Archives Commission redesign their web-based delivery of services.
